Physics Prefixes

Hence when you take the measurement the number that is obtained might be unusually large or small so that it is difficult to work with them.

Physics prefixes. The micro prefix is actually represented by the greek letter mu but is represented as u throughout these pages. The deca prefix is sometimes written deka and is abbreviated dk. See the physics alphabet the abbreviations below are those accepted by scientists all over the world as a short hand way of writing multiples of a value. Terms in this set 11 micro u 10 6.

Spellings may vary but its official symbol is always da not dk. All si units except the one for mass kg have no prefix before them. Because multiple prefixes may not be used in the case of the kilogram the prefix names of table 5 are used with the unit name gram and the prefix symbols are used with the unit symbol g with this exception any si prefix may be used with any si unit including the degree celsius and its symbol c. Commonly used unit prefixes in physics problems.

Prefixes are used for easier recording since it is complicated to write too large or too small numbers with a lot of zeros. Thus when we measure some of the magnitudes such as space distance in the universe or the size of the molecules or atoms and subatomic particles it is easier to use prefixes. Prefixes in physics you have seen in a previous post that physical quantities are properties of an object that can be measured with a measuring instrument. 1 cm 0 01 metre 1 kg 1000 grams 1 gb 1 000 000 000 bytes 0 000 0052 s 5 2μs 5 2 μ s 5 2 10 6 s 5 2 10 6 s.
